Thumbnail Filmstrip of 250 ul Micro-Insert, 31x6mm for 9mm Vials, Conical Bottom, 100/Pk Images
250 ul Micro-Insert, 31x6mm for 9mm Vials, Conical Bottom, 100/Pk - CV2046
Combining a precision glass shell with a bonded micro-insert, Tisch CV2046 vials eliminate the alignment issues associated with loose insert configurations. Conical insert geometry channels the sample toward the needle tip, maximizing recovery from volumes as low as 150µL without repositioning or specialized autosampler settings. Stringent manufacturing tolerances across vials, caps, and septa ensure that every component in the sample containment chain performs to the specifications modern analytical methods demand.
Whether running routine QC sequences or method development campaigns, your confidence in sample integrity begins with the vial system on the autosampler tray. Bonded insert construction gives you the consistent needle-to-sample positioning that loose inserts cannot guarantee, improving injection precision across your full sequence. Invest in the injection-to-injection reproducibility your laboratory depends on by specifying consumables that match the quality standards of your analytical workflow.

- Method Development - Reduced sample requirement per injection accelerates method optimization when reference standards are quantity-limited.
- Metabolite Identification - Low-volume capability supports injection of concentrated extracts without dilution-related sensitivity losses.
- Trace-Level Quantitation - Conical micro-insert geometry channels limited sample volume to the needle tip for maximum analyte recovery.
- Precious Sample Recovery - Integrated insert eliminates the dead-volume losses that compromise quantitation of irreplaceable research specimens.
- Stability Study Samples - Micro-volume design accommodates the small aliquots pulled from time-point stability testing protocols.
- Pediatric Bioanalysis - Reduced dead volume enables accurate injection from the sub-milliliter specimen volumes typical in pediatric studies.
